One caveat about HP & Dell LTs is there 3 wire power supply. You can NOT use an aftermarket power supply with them. I like running a after market DC-DC power supply in the MH. With a HP or Dell, you'll need to fire up an inverter when off grid.

I've had 3 HP laptops and 2 Dells that all had the ability to run off a 12V power supply that was available. same plug as the HP, just a 12V input to the charger instead of 120V. In fact two of the HP's had chargers that accepted either 12V or 120V inputs.
